Home > High frequency measurements from Mount Fleming Meteorological Station (FLMM) in Wright Valley, Antarctica from 2011 to present

Summary

Abstract:

As part of the McMurdo Dry Valleys Long Term Ecological Research program, meteorological data are collected from various locations throughout the McMurdo Dry Valleys of Antarctica. This data package contains 15-minute data from the Mount Fleming Meteorological Station (FLMM), located at the head of Wright Valley.

Date Range:

January 8, 2011 to December 18, 2018

Purpose:

Meteorological data are collected year-round at each of MCM LTER stations. Data are manually downloaded from the meteorological stations during the austral summer. Raw 15 minute data (Level 0) is processed and provided as Level 1 data on the MCM LTER website. Field notes, sensor information, processing procedures, QA/QC, and metadata is provided in the Meteorological Post Processing Documentation and Task Lists for each field season at the following address: http://www.mcmlter.org/data/meteorology/tasks/task_lists.htm[19]

Methods:

The Mt. Fleming meteorological station was added to the McMurdo Dry Valley network in the 1995-1996 field season. It was established on the shore of Mt. Fleming in Victoria Valley, one of the largest lakes in the dry valleys, recently discovered to have a 19 m ice cover over a hypersaline brine of undetermined depth. The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every 15 minutes. This has resulted in approximately 20 values being recorded for final storage in every output interval.

Swapped out pressure with old sensor. Was not sure new one was working, which it was. Need to replace again next season.

Loaded new program, FLMM_201112_v2.dld at 12/14/2011 @ 1515. Corrected mistaking in radio timing. Moved wire from C8 to C7, wrong location for turning the SwCtrl12V. Rotated radio antenna 10 degrees CW. Still no success connecting with the hub at Vanda
